California Adopts Low-Carbon Fuel Standard

Good. The California Air Resources Board has adopted the nation’s first mandate to lower the carbon in fuel. As these things go, it’s pretty mild: a 10% reduction in carbon footprint by 2020.

Climate Change Legislation: Is the Train (Finally) Leaving the Station?

I posted yesterday about Rep. Boehner’s bone-headed statement about climate change.  My first thought was that this was completely idiotic, making a childish argument that even George W.

Low-hanging carbon

I’m looking forward to hearing Scripps climate scientist Veerabhadran Ramanathan speak at an event next week in Los Angeles, and I hope he’ll talk about black carbon, which many are calling the low-hanging fruit of the climate change problem.  Black carbon is the fine black soot that’s generated by carbon combustion, these days mostly from traditional cookstoves and …

This beautiful spring day seems an appropriate occasion to think about the changing of the seasons.  That’s coming earlier and earlier these days.
